SPECIFICATION forming part of Letters Patent No. 418,951, dated January'7, 1890.

Application tiled July 27,1889. Serial No. 318,884. (No model.)

To all whom it may concern:

Be it known that I, JAMES JENSEN, of Park 4 Place, in the county of Leeand State of Arkansas, have invented a new and Improved Breechv-LoadingGun, of which the following is a full, clear, and exact description.

This invention relates to breech-loading guns, the main objects of theinvention being to provide for the secure locking of the gunbarrels whensuch barrels are moved to the firing position, to provide for the holding back of the retaining-bolt after such bolthas been withdrawn torelease the barrels, and to improve the action of the extractor.

To the ends named the invention consists, essentially, of a barrelformed with a projection, a bolt arranged to engage said projection,aspring arranged in connection with the bolt, a catch by which the boltis held in the retracted position, a slide, a catch arranged inconnection therewith, a thumbpiece arranged in connection with the catchand carried by the slide, and a lever that is connected to the slide andto the bolt, all as will be hereinafter more fully described, and

specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar gures and letters of referenceindicate corresponding parts in all the views. y

Figure 1 is acentral sectional view of my improved breech-loading gun,the parts being represented as they appear when the barrels are in thefiring position. Eig. 2 is a similar view, the parts, however, beingrepresented as they appear when the barrel has been movedto theextracting and loading position, Figs. 1 and 2 being taken on line 1 1of Fig. 3; and Fig. 3 is a view of the butt-end of the barrel,representing the same as it appears when removed from the stock.

In the drawings, 10 represents the actionframe and 11 the barrels.Vithin the frame 10, I mount a lever 12, the lower end of said leverbeing pivotally connected to a lockingbolt 13, which is normally held inthe position in which it is shown in Fig. 1 by a spiral spring 14, saidspring being coiled about a rearwardly-extending stem 15,-t-hat is madeintegral with or rigidly connected to the bolt 13, the spring abuttingagainst a stop 16,

and against a shoulder 17, formed upon the boli. The upper end of thelever 12 is pivotally connected to a slide 20, to which there is securedabracket 21, said bracket being arranged upon the outside of the frameand being connected to the slide by means of a downwardly-extendingprojection 22.

To the slide 2O tl1ere is pivotally connected a catch 24, which isnormally held in the position in which it is shown in Eig. 1 by a spring25, and just above the rear end of the catch 24, I mount a thumb-piece26, said thumb-piece being supported within a slot formed in the bracket21, and being formed with a downwardly-extending spur 27, which bearsagainst the upper face of the catch 24., and with a milled or serratedface 28, against which the thumb of the operator is placed.

Beneath the bolt 13, I arrange a catch-sprin g 30, the purpose of whichwill be hereinafter explained. The gun-barrels 11 are formed with adownwardly-extending and recessed projection 3l, in which there ismounted a bell-crank lever 32, one arm of said lever exi en ding` to therear, while the other arm enters a slot 33, that is formed in the mainIstem 34. of the extractor 35, the extractor being guided by an auxiliarystem 36, which rides in aproper aperture formed in the filling betweenthe barrels. We will suppose the parts to be in the position in whichthey are shown in Fig. 1. Then, itthe thumb-piece 26 be moved in thedirection of the arrow shown in connection therewith, the projection 27will be carried downward and will act to throw the catch 24 fromengagement with a shoulder b, that is formed upon the frame 10, anycontinued pressure upon the thu mb-piece acting to move the slide 2Otoward the barrels, and as the slide so moves the lever 12 will berocked, as indicated by the arrow shown in Fig. 1, and the bolt 13 willbe moved backward out of engagement with the barrel projection 31, thebolt being caught by the spring-catch 30 after it has been thrown fullyinward, and the parts being held in the position in which they are shownin Fig. 2.l After the bolt has been withdrawn the barrels may be tiltedas indicated, and as they are so tilted the projection c of the lever 32will bear against the frame-shoulder d and the lever will be rocked, andin rocking will IOO force the extractor outward to the position in whichit is shown in Fig. 2. In returning the barrels to their normalpositions the shoulder e, formed on the barrel projection 31, willstrike against the upwardly-extending section of the catch-spring andWill force said spring downward, thus permitting the spring 14 to act todraw the bolt 13 forward and into engagement with therearwardly-extending section of the projection 3l.

By means of the construction above described I obtain a perfectly securelocking of the barrels in the tiring position, and I provide for theeasy closing of the barrels after they have been moved to the loadingposition, inasmuch as I am not required to force the bolt 13 backagainst the tension of its spring 14. Havingthus described my invention,I claim as'new and desire to secure by Letters Patentl. In abreech-loading gun, the combination, with a barrel formed with arearwardlyextending projection, and a spring-actuated bolt for engagingthe said projection, of a slide, a pivoted lever having one endconnected to the bolt and its other end to the slide, and aspring-actuated catch carried by the slide and locking it againstforward move-A ment, substantially as described.

In a breech-loading gun, thecombinal tion, with a locking-bolt and its spring, of a lever pivotallyconnected to the bolt, a slide connected to the lever, a spring-actuatedcatch carried by the slide, a bracket connected to the slide, and athumb-piece connected to the bracket and formed with a pro! jectionWhich bears upon the catch, substantially as described, Y

4. In a breech-loading gun, the combination, with the barrels, of abell-crank lever 32, an extractor formed with a main stein that isengaged by one arm of the said lever, and a frame projection againstwhich the other arm of the lever bears when the barrel is tilted,substantially as described.
